The magnificence of the Colosseum is an amazing sight to behold as you walk up the street to meet it.
The first time that I visited the Colosseum I did not take any tours and just enjoyed walking around and admiring the views. The second time that I visited I went on a guided tour. The tour took us through the Colosseum and then through the grounds around the Colosseum. The tour turned out to be wonderful, even though I was a bit intimidated at first by all the people trying to sell me their guided tours. Who knows if any of them were really scammers. It proved to be a good choice though. I was happy to go on the tour and learn about the Colosseum and other interesting historical tidbits.
